Cold rolling and recrystallization textures of a Ni-5 at.% W alloy

The formation of recrystallization texture has been studied in a sintered Ni 5 at.% W alloy after heavy cold rolling (similar to 95%) and annealing. Although the colf-rolled texture is a typical pure metal or Cu-type deformation texture on a global scale, variation in microstructure and microtexture are found in the deformed material between locally sheared regions and away those from these regions. The primary recrystallization texture consists of the cube (vertical bar 100 vertical bar < 001 >), a RD-rotated cube (vertical bar 013 vertical bar < 100 >) and twin-related orientations of these two components. The presence of both cube and the RD-rotated orientations are identified in thin bands of materials in the deformed matrix. However, predominantly cube-oriented grains nucleate and grow in regions away from the locally sheared regions. In contrast, Ni 5 at% W alloy appears to occur primarily via the oriented nucleation of cube grians owing to the special properties of the cube bands. (C) 2009 Acta Materialia Inc.
